OEM Carrier Control Transformer 60VA 115/208/230V–24V for Model PH13NR03600GAFAA

This is the factory OEM control transformer for the Carrier PH13NR03600GAFAA heat pump system. The transformer steps down high-voltage line power (115, 208, or 230V) to the 24V AC signal that drives your thermostat, contactor coil, and every control board relay in the system. When this part fails, the entire low-voltage control circuit goes dark — your thermostat shows blank or no response, the contactor never pulls in, and the system won't operate in any mode. It is one of the first components to test when a unit shows zero response despite confirmed line voltage at the disconnect.

  • Specs: 60 VA power rating | 115/208/230V AC primary (multi-tap) | 24V AC secondary | 50/60 Hz | Foot-mount chassis | OEM part number HT01AW229
  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part — not an aftermarket substitute. OEM transformers are wound to exact VA and impedance specs. Undersized or off-tolerance generics can overheat, nuisance-trip thermal cutoffs, or fail to hold contactors under full load.
  • Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before proceeding. Tools needed: multimeter, flathead and Phillips screwdrivers, wire stripper, and needle-nose pliers. Confirm primary tap wiring matches your supply voltage (115V, 208V, or 230V) before energizing. Photograph all wiring before disconnecting the old unit.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PH13NR03600GAFAA heat pump systems. Also cross-references under part number HT01AW229A. Verify your unit's supply voltage and confirm the 60VA/24V secondary rating on your existing transformer's data label before ordering. Have fitment questions?

Frequently Asked Questions

Does this Transformer fit my Carrier PH13NR03600GAFAA?
Yes. This is the factory-specified OEM transformer for the Carrier PH13NR03600GAFAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the transformer on my Carrier PH13NR03600GAFAA?
Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Photo wiring connections. Step 3: Disconnect wires from old transformer. Step 4: Remove mounting hardware. Step 5: Install new transformer, reconnect wires matching voltage ratings. Step 6: Verify 24V output with multimeter.
My thermostat has no power. What failed?
Thermostat with no display = failed 24V transformer (or blown control board fuse). Check the 3A/5A fuse on the control board first ($1–$5 fix). If fuse is good but no 24V output from transformer, replace transformer.
Is this transformer compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier transformer?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
How fast does National HVAC Parts ship?
